Coal depletion is the inescapable result of extracting and consuming coal since it is a finite resource. The number of years of coal left is estimated by the ratio of proven coal reserves to the current consumption rate.

[edit] When will coal run out?

Assuming the current rate of consumption and that there are still an estimated 909 billion tonnes of proven coal reserves worldwide, there is enough coal to last at least 155 years.^[1][2]
